MACHINE FOR ASSEMBLING THE PARTS OF BUTT-HINGES AND THE LIKE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

To all whom it may concern:

Be it known that we, I-IERMANN STELLER and RUDoLr PIEPENSTOOK, subjectsof the Emperor of Germany, and both residents of Oeckinghausen, nearKarthausen, Westphalia, Germany, have invented a Machine for Assemblingthe Parts of Butt-Hinges and the Like, of which the following is aspecification.

The present invention relates to a machine by means of which the partsof butt hinges as well as other hinges, and the like, are automaticallyassembled. The parts of the hinges, viz., the flaps, the pins and theknobs are fed through inclined channels onto a table where, by means oframs and slides, the two flaps of the hinge are joined to their knobsand secured to the hinge pin. Finally, the completed hinge isautomatically expelled from the machine. All these operations areeffected automatically and no other hand-work is required than thedeposition of the parts into the feeding channels. Such deposition may,if desired, also be automatically efiected.

In the accompanying drawing the invention is illustrated, Figure 1representing a plan of the machine, some parts thereof being shown bybroken lines only, for the sake of clearness, Fig. 2, a side View of thesame, Fig. 3, a cross-section on the line AA of Fig. 1, and Fig. 4, aView of one of the de tails of the machine.

The mechanical elements of the machine are arranged on a table top 1which is supported on legs 2. On said table top four rams 3, 4, 5 and 6are arranged in horizontal position and in such a manner that each ramis parallel to another and in alinement with a third. The rams areslidably guided by means of their holders in bed-plates 7 and are movedin axial direction by eccentrics 8 slidably guided on the table top atright angles to the rams. The slides are tensioned, together with thelevers, by springs 23, and the levels engage the cams by means ofrollers 20.

The various hinge-parts are fed onto the table top by means of inclinedfeeding channels 24, 25, 26, 27 and 28 which in Fig. l are shown bybroken lines only. Any known automatic device may, if desired, beprovided for supplying the hinge-parts to the channels. The channels areopen at their lower ends so that the lowermost hinge-part always restson the table top or on the special supporting plate provided thereon forthe purpose.

The holder of the ram 5 has an off-set arm 31 connected thereto whicharm, at the movement of the holder, engages the hingefiap 32 protrudingthrough the channel 27 and places the same in front of the slide 21.Thereupon the latter moves and advances the flap so that its eye getsinto alinement with the rams 3 and 5. These rams then approach oneanother, the former carrying with it a pin 30 from the feeding channel28, and the latter a knob 29 from the channel 25. Both these elementsare forcedby the ram into the eye of the flap 32 and secured thereto,the knob with its stem and the pin with half its length. The slide 21acts on the flap by means of a U-shaped frame, the member 38 of which isdisposed so as to move clear of the flap as long as no knob or pin isconnected thereto. Down-turned lugs 39 (Fig. 4), however, while movingclear of the flap itself, engage the knob and the pin when these havebeen connected to the flap. After such connection, therefore, the flapwill be advanced by the arm 38 so that the hinge pin gets into alinementwith the rams 4 and 6. These rams, which have been at work meanwhile,now complete the hinge. An off-set arm 40, connected to the holder ofthe ram 4, engages the flap 32 protruding through the end of the feedingchannel 26 and passes the same within reach of the arm 41 connected tothe slide 22 which arm advances it into alinement with the rams 4 and 6.At the subsequent movement of the rams, the ram 4 takes a knob 29 fromthe end of the feeding channel 24 and forces said knob into the eye ofthe flap 32 simultaneously with forcing the latter on the hinge pin ofthe flap 32 which is disposed in the path. Finally the completed hingeis expelled from the machine by an arm 48, connected to a right-angledextension on the arm 41, and deposited through an aperture 44 in thetable top into a suitable receptacle. The arms 41 and 43 are disposed soas to keep clear of the flaps themselves and advance them by engagementwith the eyes.

In order to secure the flaps firmly in position while the rams operate,the following arrangement is provided: A plate 35 is adapted to rockabout a shaft 34, the rocking being eflected by a cam 87 mounted on theshaft 13 and cooperating with a spring 36. Lugs 33 and 42 on the freeend of the plate are disposed so as to place themselves over the eyes ofthe hinge-flaps and prevent lateral movements of the same when the plateis acted upon by the cam 37. This is done simultaneously with theoperation of the rams. The engaging surfaces of the lugs are grooved, asshown in Fig. 3, to coincide with the eyes, a firm hold on the flapsbeing thereby obtained. The paths followed by the various hinge-parts onthe table, particularly those of the knobs 29 and of the pins 30, arealso grooved so that no spontaneous movement of the elements takesplace. The movements of the rams and of the slides are regulated so thatthe hinge-parts are put through the various stages of the operation indue order. While the rams operate for connecting the parts fed intoalinement with the same, the arms 31 and 40 feed fresh flaps into reachof the slides 21 and 22. The slide 21, while feeding one flap intoalinement with the rams 3 and 5, feeds the previous one into alinementwith the rams 4 and 6 by means of its arm 38. Similarly, the slide 22,while feeding one flap, by means of its arm 41, into alinement with therams 4 and 6, expels the previously completed hinge from the machine bymeans of its arm 48. After the return movement of the rams and theirarms, a fresh pin and fresh flaps and knobs are fed by the channels intooperative position. In order to enable the elements to be correctlyadjusted and to adapt the machine for hinges'of various sizes, the ramsare connected to their holders by means of screws 46 passed throughlongitudinal slots 45. For the same purpose the slides 21 and 22 areconnected to the levers 19 by means of adjusting screws 47.

The described construction and combination of the elements may bemodified within the scope of the appended claims without departing fromthe spirit of the invention. Machines of correspondingly modifiedconstruction may be used for the assembling of other kinds of hinges.

We claim 1. A machine for assembling the parts of butt hinges and thelike, comprising a table, inclined feeding channels for feeding thevarious hinge parts onto the table top, two pairs of horizontallymovable co-axial rams arranged on the table top, one ram of each pairhaving an off-set arm adapted to move the lowest flap away from afeeding channel, a slide for moving one of the discharged flaps so thatits eye gets into alinement with one pair of rams and for simultaneouslymoving the flap previously operated upon by the rams into alinement withthe other pair of rams, a slide for moving the flap discharged from theother channel into alinement with the second pair of rams and forsimultaneously expelling the completed hinge from the machine, means forguiding the hinge pin and knobs so that a pin and a knob are connectedby the first pair of rams to one flap and so that another flap isconnected to the same pin and a knob to the other flap by the secondpair of rams, shafts having eccentrics for operating the rams, cams atone end of the shafts, levers acted upon by said cams for operating theslides, a driving shaft, and connections between said driving shaft andthe aforementioned shafts for operating the latter, substantially as setforth.
